Thanks for the detailed analysis. I do not think the long -I
(actually, not PERL5LIB) is the cause, too. It is not too long yet
(131 modules) for Unix shells. The real cause may sit somewhere else.
But still, the -I list repeating itself 3 times is not right. 131
modules result in 131x2x3=786 arguments, which cause the real error
message being truncated. And, without the clue of the root testing
module, I can hardly replay the error and diagnosis the problem.
Is it possible that when tracking the dependency, the root testing
module is also recorded in the test reports?
Is it possible to check and avoid duplicates when attaching include
directories?
